The oxidation process occurring in the liver rids the bloodstream the alcohol present

The oxidation process gets rid of about 90% of the alcohol present in the bloodstream. since the oxidation process cannot get rid of all the alcohol in your body, the other organs must step up to help. the kidney helps to eliminate about 5% of the alcohol through urination, while the lungs get rid of the last 5% through exhaling. the exhalation of alcohol allows police officers to see if you have alcohol in your system through breathalyzers.

20 times a minute is usually the average respritory rate of an adult. additionally the patient is breathing on his own, is clearly maintaining his airway, and is intaking a sufficient amount of air. you shouldn't use a bag valve mask, cpap, or other form of positive pressure ventilation, unless the patient has lost control of his airway, and is not breathing (apneic) or has rapid breathing or slow and shallow respirations. this patient would most likely and should be put on an non-rebreather mask or nrb attached to 100% high flow oxygen at 15 l/min. don't use a nasal cannula, as the amount of oxygen it provides is limited with a rate of 6 l/min.
